J/id>. Madagascar and East Africa, from the Zambesi north to

I am unable to determine what the Charadrius marginatus of 

 Heuglin (VSg. N.O.-Afr. ii. pt. 1, p. 1031, tab. xxxiv. tig. 6) can 

 be, from the Red Sea, Dahlak Archipelago, and Jeddah. As At. 

 ti tu I In ranges as far as Lindi, it is extremely probable that it extends 

 northwards to the Red Sea.

* Dr. Gadow has kindly sent me the type of this species Cor examination, 

 that I find that it must be the winter plumage of M. tenclla, over which name 

 and "f JE. pallida takes precedence.
